Garbage app and service
Response from developer
We have changed the implementation of the cancel all and flatten feature in version 1.6.0.0. As long as your device maintains its connection to Rithmic’s trading infrastructure while your request to cancel all and flatten is sent and received, your request should be handled. We are planning to release a new version this month which will implement an auto-reconnection mechanism in the event that the connection between a mobile device or a browser and Rithmic’s market data and trading infrastructure is dropped.
